Abstract

PURPOSE: To obtain the gas sensing element excellent in the gas detection sensitivity and high temperature stability, by using the silicon nitride giving compound selected from specific metal compound to the gas sensing substance made of metal oxide semiconductor as catalyzer.
CONSTITUTION: Catalyzer is obtained by adding and mixing H2PtCl2.6H2O or PtCl2 solution to silicon nitride powder and immersing it under reduced pressure and drying and sintering it. Next, the said catalyzer is added to the metal oxide semiconductor of ZnO-Cr2O2 system and mixing is made by blending the binder such as methylcellulose to obtain paste. This paste is coated on the surface of the cylindrical insulator 1, and it is sintered at 300W1000°C after drying to obtain the gas sensing element. The compound constituting the catalyzer is Pt, Pd, Rh, Re or selected one from the compound one or more, and the amount of catalyzer is suited to the silicon nitride for 0.05W10wt%.
